Hey all;-
I have seen (collected) several Olive shells in South Carolina with just such Bryozoan colonies attached. They can generally be removed in one piece. I haven't found any of them inhabited by crabs. Perhaps it is because the Olives are too heavy for their siize for the crab to move in comfortably. I suppose the colonies would also grow on whelks---but I haven't noticed.
